Groundforce Shorco has supplied a full complement of trench support equipment, including ladders and ancillary components, to contractors carrying out a major improvement to waste-water treatment facilities in Derbyshire.
Main contractor NMC Nomenca (a specialist division of North Midland Construction) is building a new sewage pumping station in the village of Fenny Bentley for Severn Trent Water.
The new facility will replace the existing pumping station which has reached the end of its working life. At the same time, the existing Fenny Bentley treatment works, which is also life-expired, will be demolished.
The new pumping station will divert flows, via a new sewer, to Severn Trent’s Ashbourne treatment works, 4km away.
As part of the project, NMC Nomenca is installing the new sewer which comprises a 125mm diameter rising main. This 1km pipeline feeds into an existing gravity sewer to Ashbourne.
To accommodate fluctuations in both sewage flows and surface-water run-off, NMC is installing a storage pipe, comprising 350m of 1,050mm diameter concrete pipe, in-line with the existing sewer.
The small-diameter rising main has been installed using trenchless techniques by specialist JMH Directional Drilling. “Each run is between 100 – 150m and JMH need a launch pit from which to drill and a reception pit at the other end so they can pull the new pipe through,” explains Tony Duerden, NMC’s site manager.
Groundforce Shorco supplied its Backhoe Trench Boxes, Endsafe panels and access ladders to support the sides and ends of these 2.0m x 2.5m x 2.5m deep pits and ensure safe working.
Downstream, where subcontractor Clumber Construction is installing the concrete storage pipe, Groundforce has supplied its Standard Trench Boxes, 3.5m Manhole Boxes and Pipe-Lifter.
“It’s a fairly standard job, using standard equipment, but we are one of the few companies that can meet the requirements of a client like NMC,” says Groundforce Shorco Technical Sales Representative Darren Boote.
“The big advantage we have is the range of equipment and its availability. We are one of NMC Nomenca’s preferred suppliers because they know we can respond quickly and with the ideal solution,” adds Darren.
Work began on the pipeline in October 2016 and completed in May 2017
